Beginning this week we won't have time -- at least most of us won't -- to do enough work on individual quarterly reports as they happen. The next three weeks will be sheer hell, and I am always amazed when generalists have claimed they've seen more than just the cheat sheet of the reports -- the CliffsNotes, so to speak.

But last week was different. If you took the time out to read the report of Wells Fargo (WFC) -- and, believe me, there was time to do it -- you would have been pretty much stunned at how much business it's doing and at how strong the mortgage business is in the U.S.

• Mortgage business revenue was up 90% from a year earlier and 11% from the prior quarter.
• Revenue from refinancing was up more than $19 billion, or 43%, from the first quarter, "indicating continued strength in the overall housing market, where we see increases in sales and pricing in markets throughout the country, even some of the hardest hit areas during the slowdown," according to CEO John Stumpf.
• A 31% increase was achieved in commercial loan growth, through portfolio acquisitions and organically increased credit card penetration.
• Credit quality continued to improve, with the charge-off ratio declining to 1.15%, the lowest since 2007.
• Nonperforming assets declined by $1.8 billion from the first quarter, down 11% from a year earlier.
• Record net income rose by 17%, with earnings per share up 17% from a year earlier.
• "Mortgage volumes have been much stronger than anyone expected a year ago or even three months ago, for that matter, with originations more than double where they were a year ago, and our mortgage pipeline, which should lead to future revenue and expense growth, has also doubled," according to CFO Timothy Sloan.

These are astounding numbers. They're the kinds of numbers that signal a gathering strength in housing, something that few people expected and fewer still had thought possible, given that the economy was supposed to have hit a wall a few months ago.

When the largest bank for mortgages reports these numbers, you simply have to rule out the kind of slowdown the employment numbers suggest to us. You have to conclude otherwise. The numbers from Wells are just too big.

I have been a believer in Wells ever since the bank got its arms around the portfolio it bought from Golden West via Wachovia.

That deal -- which no one, other than Wells Fargo, would ever admit was cheap -- now does look incredibly intelligent for this simple reason: The amount of national coverage Wells bought otherwise never would have been allowed by regulators. Wells basically got control over most of the country's mortgage market and servicing market. It services an astounding $1.9 trillion in residential mortgages, with an amazing ability to cross-sell, in return for two years of outsized losses.

Put simply, Wells Fargo is telling you that housing is back and that it is booming and that this moribund part of the economy is now a huge tailwind, not a headwind. Can housing carry the economy? No. Can it offset sluggish employment? I'm beginning to think it can, and that's the main reason the market was able to reverse direction and go up at the end of last week. When you consider the good commercial lending by JPMorgan Chase (JPM) and the mortgage lending by Wells, you basically come back with a picture of the U.S. being in fine shape, by far the best of all economies around the world, save for China. It emerges as an economy with increasing strength, not declining strength, as we head into the second half of the year.
